Joseph,
You are an agitator. It’s a cute line you came up with: “you are mistaken”. Ive seen you use it before. don’t deny history. It doesnt serve anyone any good.
The facts are that it in no way maligned anyone by saying they didnt cover their hair bacuse at the time there was no chiyuv, the reason being as the Novordoker Rav wrote that hair is no longer a davar hamekusah. (hair covering is d’rabbanan)
If you write “you are mistaken” it will be to the aruch hashulchan, not me. Let me see you write that.
